Question

Can anyone please give me sample code of how sound is played with a UIButton being tapped?

I would like to play an MP3 file using AVAudioPlayer

Answer 1

something like this should get you started. Add this to your view controller, then hook up the button to the playAudio action in interface builder.

in your header .h

#import <AVFoundation/AVFoundation.h>

@interface ClassName {
    ...
    AVAudioPlayer *audioPlayer;
}
@property (nonatomic, retain) AVAudioPlayer *audioPlayer;

- (IBAction) playAudio;

in your .m

@synthesize audioPlayer;

- (IBAction) playAudio {
    NSURL *url = [[NSBundle mainBundle] URLForResource:@"audio" withExtension: @"m4a"];
    if (!url){NSLog(@"file not found"); return;}
    NSError *error;
    self.audioPlayer = [[[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error] autorelease];
    [audioPlayer play]
}
